Re: Implement 'AND' function with 'XOR' function. Message #5 Posted by Steve (Australia) on 13 Dec 2000, 5:55 a.m., in response to message #1 by Tal
If you were to bu trying to build an AND function from XOR gates, then it is indeed possible.
Imagine an XOR gate with one input held in a logic 1 state. The gate then acts as an inverter. Similarly, if the input is held low it acts as a non-inverting buffer.
Using an additional 2 diodes, and a resistor allows you to "wire-AND" the outputs of two buffers, and then buffer the output.
Depending on the nature of the surrounding logic, you could even dispense with the XOR gates :-)
